An accidental logic puzzle

As is usual for me on a weekend morning, I was browsing through an old newspaper that shared the same date as my current self. Today I was reading one from thirty years ago, 29th April 1987, when I noticed that the division for Group Four in the European Under-21 Championship formed a little logic puzzle: it was possible to look at it and work out all of the results of the tournament to date.

It isn't a difficult puzzle nor, I'd imagine, that unique but it kept me entertained for a few minutes. Plus, it reminded me of that example of Accidental Poetry I found several years ago.
